gtk:places-sidebar-nth-bookmark (sidebar n)

sidebar -- a gtk:places-sidebar widget
n -- an integer for the index of bookmark to query

The namestring with the bookmark specified by the index n, or nil if no such index exist. Note that the indices start at 0, even though the file chooser starts them with the keyboard shortcut Alt-1.

This function queries the bookmarks added by the user to the places sidebar, and returns one of them. This function is used by the gtk:file-chooser widget to implement the Alt-1, Alt-2, and so on, shortcuts, which activate the cooresponding bookmark.
